Beit known that I, CLARE CAHOON, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Milk-Coolers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

VMy invention relates to improvements in milk-coolers; and its object isto provide the same with certain new and useful features hereinafteilmore fully described, and particularly pointed out in the claims,reference being had to the accompanying drawings, in which- Figure l-isa front elevation of a device embodying my invention, with parts brokenaway, showing a vertical section on the line l l of Fig. 3. Fig. 2 is atransverse vertical section 0f the same on the line 2 2 of Fig. l; Fig.3, a plan View of the device with the top cover removed, and Fig. 4 thesame with the cover C also removed.

Like letters refer to like parts in all the gures.

A represents a suitable rectangular case or box having the usual doublewalls, metal lining, and hinged cover B. A short distance below thecover B is a second removable cover C, having openings near each end,through which project the upper ends of the milkcans L. Between the cansL and near the middle of the case A are two compartments G H to containice, said compartments being formed by vertical walls extending from the'bottom of the case to the cover C. These compartments are connected byopeningsJ in the upper part of the dividing-walls and also with the endspaces of the box by other openings J in the upper part of the walldividing the same from said spaces. Openings I are also formed in thelower part of the walls between the forward compartment H and the saidend spaces. Close below the cover C is a perforated cover E, closing thetop of the compartment H, and at a convenient distance from the cover Cis also a perforated cover F in the compartment G, dividing the samehorizontally into two parts. Said covers E and F may be secured bysuitable locks M to prevent removal of the ice placed in thecompartments'G'and H. An overliow-pipe K extends fromthe respective endspaces near the level of the upper part of the cans, and a drain-pipe Kconnects the bottom of the compartment G with the pipe K.

The operation of my device is as follows: The cans of milk to be cooledare placed in the spaces at the ends of the case and a suitablequantityof ice is placed in each of the compartments G and H. Water isthen poured around the cans until up to the overiowpipe K. This wateralso fills the compartment H to the same level by passing through theopenings I. The ice in the compartment H, being in direct contact withthe water, cools the same Yrapidly until near the freezing-point, whileat the same time it is confined in said com= partment and does not getin the Way of the cans should they be removed and replaced, asfrequently occurs in practice. I find, however, that it is not desirableto cool the water to such a low temperature, and also that it isdesirable to maintain a moderately low temperature for a considerabletime. I can accomplish this by so apportioning the ice that the ice inthe compartment H will do the initial cooling of the water. Then the icein the compartment G will gradually absorb the heat through the walls ofthis compartment andmelt much more slowly than if in contact with thewater, said compartment being drained free of any water by the pipe K.The ice in the same will be surrounded with non-circulating cold air. Ittherefore melts away very slowly,maintaining the water in the othercompartments at a su ficiently low temperature, but somewhat above itsown temperatureand for a long time, with but little consumption office.The upper part of the compartment G serves as a convenient receptaclefor butter, being sufliciently cool for the purpose.V

Having thus fully described my invention, what I claim, and wish tosecure by Letters Patent, is-

l. In a milk-cooler the combination of a case, a .compartment to containwater, and

milk-cans partially submerged in the water, a compartment to contain icehaving its walls contacted by the water, a drain-pipe in the bottom ofsaid compartment, and a second ice-compartment having openings into thewater-compartment to admit water from the same, substantially asdescribed.

2. In a milk-cooler the combination of a case, a compartment at each endthereof for milk-cans, and two middle compartments, a drain-pipe in thebottom of one of said middle compartments, there being openings in thesides of the other of said compartments to admit Water from the endcompartments, substantially as described. y

3. In a milk-cooler the combination of a case, a compartment at each endthereof and two middle compartments, a drain-pipe in the bottom of oneof the middle compartments, there being openings in the walls of theother middle compartment to admit water from the end compartments, adrain-pipe from near the upper part of the end compartments, there beingair-openings in the walls of said middle compartment and above thewaterlevel, substantially as described.

4. In a milk-cooler the combination of a casehaving two end and twomiddle compartments, a drain-pipe at the bottom of one of said middlecompartments, there being openings in the sides of the other of saidcompartments near the bottom and top thereof, perforated covers in eachof said middle compartments, one of said compartments being divided intotwo chambers thereby, and a removable cover above all of saidcompartments having openings for the milk-cans, and a door in said coverabove one of said middle compartments, substantially asdescribed.

In testimony whereof` I aiix my signature in presence of two witnesses.

CLARE CAHOON.
